Contractor licensing

Missouri contractor license requirements

Missouri does not issue a statewide general contractor license. Licensing happens at the city and county level, and the only statewide construction trade license is an optional electrical contractor license from the Division of Professional Registration.

There is no statewide general contractor license in Missouri. The Division of Professional Registration, which runs the state's licensing boards, has no board for general contractors, plumbers, or HVAC contractors. Its one construction trade board covers electrical contractors, and that statewide electrical license is optional. Your real licensing work happens with the cities and counties where you pull permits, plus state business registration, tax, and workers' compensation rules that apply everywhere.

Why Missouri licensing is local

Because the state does not license general building work, each city decides what it requires. A general contractor working in Kansas City, Springfield, and a rural county in the same month can face three different sets of rules. Build the local check into the job setup, the same step where you confirm the building permit path.

Kansas City

Kansas City's Permits Division, part of the City Planning and Development Department, administers contractor licensing. The city licenses by category: Demolition, Electrical, Elevator, Fire Protection, Gas-Fired Appliances, Mechanical, Operating Engineers, Plumbing, Residential Building, and Sign. Residential Building covers one- and two-family dwellings and townhomes. The process runs in order: get a city business license, apply for a Certificate of Qualification through CompassKC, then apply for the contractor license. The city also requires mechanical certifications for people supervising HVAC work, and journeyman and master plumber credentials.

Springfield

Springfield requires a City-licensed General Contractor or Trade Master to be listed on a permit before the city issues it. In most cases a licensed master in the trade must be listed, with a possible exception for a homeowner working on a residence they personally occupy. The city works from the 2018 I-codes and the 2017 National Electrical Code.

St. Louis and other jurisdictions

Outside Kansas City and Springfield, each city and county sets its own requirements, and that includes St. Louis City and St. Louis County. The details change by jurisdiction and by trade, so call the permit office or check the official city or county website before you bid. Say a drywall sub based in Columbia picks up a $220,000 tenant improvement in Clayton. The sub should confirm the county's license and insurance rules before mobilizing, not after the first inspection.

The statewide electrical contractor license

Senate Bill 240 (sections 324.900 to 324.945, RSMo) created a statewide electrical contractor license, and the Office of Statewide Electrical Contractors began accepting applications on July 1, 2019. The license is optional, not mandatory. Its value is portability: political subdivisions must recognize a statewide license in place of a local license. Permits and inspections stay local, since the state does not issue permits or inspect work.

  • Insurance and bond: proof of $500,000 in liability insurance, and a bond posted with each political subdivision where you work.
  • Exam: a standardized, nationally accredited electrical assessment exam given by a third party. Approved options include International Code Council exams through Pearson VUE, Prov exams, and NASCLA exams through PSI.
  • Experience: 12,000 verifiable practical hours, or 10,000 hours plus a DOL-approved journeyman certificate, or 8,000 hours plus an associate degree, or 4,000 supervising hours plus a four-year electrical engineering degree.
  • Local license holders: can qualify with an NEC-based exam and either 12,000 hours or local licensure for six of the previous eight calendar years.
  • One firm: each firm needs at least one statewide licensee at a supervisory level, and a licensee can represent only one firm at a time.

Fees are $200 to apply, $100 for the triennial renewal, $250 to reinstate, and $100 for a temporary license, all nonrefundable. Since January 14, 2025, applications, renewals, and payments run through MOPRO, the state's online licensing system.

Workers' comp, tax, and registration

Most Missouri employers need workers' compensation once they have five or more employees, but construction is different. Construction industry employers need coverage with one or more employees (RSMo 287.030). LLC members and corporate officers count toward the employee number; sole proprietors and partners do not. Collect a certificate of insurance from every sub, because an uninsured sub's injured worker becomes your problem.

Register your entity with the Missouri Secretary of State through Missouri Business Filings. Missouri imposes use tax on the storage, use, or consumption of tangible personal property in the state. On projects for exempt entities such as counties, political subdivisions, schools, qualifying nonprofits, and MoDOT, RSMo 144.062 exempts construction material purchases made for the project. Confirm tax treatment with the Department of Revenue for your situation.

Public work brings its own rules. See Missouri prevailing wage and Missouri prompt payment and retainage before you price a public bid.

Frequently asked questions

Do you need a contractor license in Missouri?

Not from the state for general construction. Missouri has no statewide general contractor license. Cities and counties such as Kansas City and Springfield license contractors locally, and you need to meet each one's rules where you work.

How do I look up a Missouri contractor license?

State licenses, including the statewide electrical contractor license, are searchable through the MOPRO license search at mopro.mo.gov. Local contractor licenses are checked with the city or county that issued them.

Is the Missouri statewide electrical license required?

No. The Division of Professional Registration says the statewide electrical contractor license is optional. Its benefit is that political subdivisions must accept it in place of a local license.

Do Missouri contractors need workers' comp with one employee?

Yes, for construction. Missouri requires construction industry employers to carry workers' compensation if they have one or more employees, while most other employers need it at five or more.
